Wow. I mean, my dad and I was actually talking about the same kind of thing on Friday. How information is shared with other companies.
For instance, my dad's credit score is going up, and some how now were getting lots of junk mail from places saying my dad can get a new credit card or can get a loan for a new car. It's ridiculous. It's probably the car company giving it out, haha. I don't think my dad has a Facebook. xD
I deleted mine right after I made it because it was just asking for way to much details about a person and plus it's ugly.
